freightliner fc80 with cummins 5.9 engine...will it tow?

I would not be cranking up a 5.9 in a medium duty application. Just use it at the factory rating until you make enough money to buy something better.

Love the 6bt and 4bt, but thats allot of truck. If your ok with 55 mph, go for it

Yet another case of trying to use a light duty engine for heavy duty work. Sure a 5.9 can be juiced to do it and it will not make 150000 turned up working its stones off. You need like stated a m11 or a c12.

Personally if I where in your shoes I'd want something 400 plus horses. I like to be to the top of the mountain first!

We have a C12; runs really clean & ‘okay’ hold back on the Jake’s…not like a Cummins but decent. Also really good on fuel for the light loads we haul.

We've been running on for 13 years in our tandems (same engine in 2 different trucks) set at 445 and 1650 turque witch is it for factory ish settings. Not a complaint other then the liners leaking coolant due to the single liner oring design. Knock on wood the 2 bottles of bars leak is working great. I'd go hope in it and head across the contry this second!
